BOLTlNG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 255,002, dated March1.4, 1882.

Application filed Octobtr 8, 1881.

To all whom it may concern Be it known thatI, OavILLn M. Mossa, ofSpringville, in the county of Erie and State of New York, have inventednew and useful Improvementsiu Bolting Apparatus, ofwhich the followingis a specification.

This invention relates to thatclass of boilingmachines which areprovided with an inclined bolting-surface and au elevating mechanismwhich faces the boltiug-surface, whereby the material to he bolted isrepeatedly elevated and caused to tlow over the bolting-surface. l/Vhenbolting very ne material-forinstance, meal which has been deprived ofthe bran-the meshes ofthe bolting-cloth are liable to become more orless filled, whereby the operation ol themachinc is impaired and itsbolting capacity reduced.

The object of my invention is to obviate this difficulty and to renderthe machine otherwise more reliable and uniformin its operation.

i My invention consists to that end of the pe- 'culiar mechanism wherebythe meshes of the bolting-cloth are kept open, also, of the peculiarconstruction of the elevating mechanism, and of the means whereby theelevating mechanism is prevented from clogging; also, of the meanswhereby the low of the material over the bolting-surface is controlled,as will -be hereinafter iully set i'orth.

In `the accompanying drawings, consisting of four sheets, Figure l isafront elevation of my improved bolting apparatus with a part of theease broken away. Fig. 2 is a top plan view thereof with a portion ofthecase broken away. Fig. 3 is a cross-section of the machine in line w x,Fig. 2. Fig. 4 is au elevation ot' the tail end ofthe machine. Fig. 5 isan enlarged cross-section of the lower part of the machine. Fig. Gis anenlarged cross-section of the upper portion ofthe bolting-surface andconnecting parts. Fig. 7 is a longitudinal sectional elevation of themachine. Fig. S is a horizontal section fof the bolting-screcn andWipers. Fig. 9^is a top planview of the belt and connecting partswhereby the wipers are operated. Fig. 10 is an elevation of the head endof the machine. Fig. 11 is an inside sectional elevation of the upperfront portion of the machine.

(No model.)

Lilie letters of reference refer to like parts in the several figures.

A represents the inclosing case ofthe machine, secured to the frame A',both constructed in any suitable and well-known manner.

B represents the inclined boltiug-screen, consistin g preferably of asuitable num ber ot'screensections, covered with boltiug-cloth of propermesh, and arranged side by side between horizontal ways b b', which aresecured to the frame A of the machine.

l2 are openings formed in the case A, between both ends of the ways b,(Figs. 4 and 10,) for inserting and removing the screen-sections.

C represents the meal-chamber above the screen B, in which the elevatingmechanism is arranged; and D represents the flour-chamber underneath thescreen, which receives the material which passes through the screen, andwhich is provided with two conveyers. D D2, having cut-offs or slides d,whereby different grades of the sifted material can be commingled or bedrawn olf separately at desire.

E represents a wiper or brush frame arranged to travel back and forthover the upper surface of the screen B. This frame is provided, as shownin Fig. 8, with tlexible strips e, of rubber or similar material, whichbear against the bol-ting-cloth and remove the material which may adherethereto. Two strips, e, are preferably arranged near together, wherebythe rst strip will remove the material lying ou the cloth, while thestrip following immediately after the first strip will bear upon theclean cloth and thoroughly dislodge the material which is contained inthe meshes of the cloth. The frame E is made ofwood and very light, sothat the pressure which the strips c exert upon the cloth is justsufficient to clean the cloth without, however, wearing or abrading thesame. The frame Eis preferably made about halt' as long as theboltingsieve B, so that its movement equals one-half the length of theboltingsurface. The frame Eis supported by two bars, f, which projectupward and hook over and slide on ahorizont-al rail or bar, f', securedto the casing of the machine in front of a horizontal slot', f2, formedin the front side of the casing. The frame E is op erated bya horizontalendless belt, G, arranged at the front side ot' the machine near theslot f2. The belt G runs over two pulleys, gg', and is connected with anupwardly-projeeting arm, f3, ot' the fra-nie E by a cord, chain, orrope, g2, whereby the frame E is drawn back and forth over thebolting-cloth. The pulley g is secured to a short shaft, which turns ina bracket, h, and which carries at its outer end a bevel-wheel. 7L. Thelatter is Vdriven by a bevel-pinion, h2, which is secured to the innerend of a horizontal shaft,v h3, its outer end being provided with apulley, H, to which motion is communicated by an endless belt, h4, froma pulley, h5, mounted on the upper shaft of the elevating mechanism. Thepulley g turns loosely on an arboror stud, which is secured to abracket, g3. Both pulleys are free or unobstructed at their innersides., so that the chain g2 can pass freely around the pulley with thebelt.

I represents a wiperor brush fratrie arranged to traverse the lowersurface of the boltingscreen B. This frame is provided with a number ofupright bars, 1', which project into the panels or recesses formed onthe under side ot' the bolting-screen B by the frames of the severalscreen-sections. The lateral movement of the frame I 'is limited to thelength of one of these panels, anda wiper, t', is provided for eachpanel, which it is necessary to clean by such means. The lowerhorizontal piece, t2, ot' theframel is guided on arail, t3, securedtothe casing of the hour-chamber D, and the vupper horizontal piece, it,of the frame I is guided by means ot' earsj,which project downward fromthe casing. The horizontal top piece,t4, is preferably provided at itsouter side with notches j', which permit the upperend of the .frame I todrop forward when it arrives at either end of its movement, therebyholding i the wipers away from the bolting-cloth While the frame I isstationary', and preventing the cloth from becoming worn by vibratingagainst the wipers. The fratrie I is operated by a chain, rope, or cord,j2, which connects the frame with the endless belt G, and which hassufficient slack or excess ot1 length to move the frame I only thelength of one panel in each direction.

K represents a knocker, which is secured with its upper end to the frameof the machine, and which bears with its lower end against thebolting-sieve B.

k represents one or more springs, applied to the opposite end ot' thesieve B, for the purpose ot' jarring the same in connection with theknocker. The kncker is operated by a wheel, 702, provided with asuitable number of removable pins, which can be inserted or removed atpleasure, and whereby the knocker can be operated one or more times atevery revolution of the wheel, as may be desired. The wheel 7a2 ismounted on a shaft, Z, which is rotated by means of bevel-wheels l Z2from the lower shaft of the elevating mechanism.

' the machine.

M represents the driving-pulley, from which motion is transmitted by apinion,mf, to a gearwheel, m', mounted on the lower shaft, m2, of theelevating mechanism.

n represents a gear-wheel, which is mounted on the opposite end of theshaft m2, and which transmits motion to the conveyers D D2 by means ofan idler-wheel, n', and gear-wheels n2 n3.

As shown in the drawings, the elevating mechanism consists of threeendless belts, 0 o o2, provided with buckets p. The belts run over ahead-pulley or drum, P, which is provided with journals p', turning inbearings p2, attached to the frame A. qq g2 represent the lower' pulleysoftheelevating mechanism. rIhe pulley q is tirmly secured to the shaftm2, which turns in bearings Q' Q2, and the pulleys g q2 turn loosely onthe shaft m2, whereby each of the three belts is enabled to moveindependentiy of the other belts, so that if either belt should moveslightly faster or slower than the other belts the parts will not bind.The bucketsp are arranged most closely together on the head-belt o, lessclosely on the second belt, 0", and farthest apart on the tail-belt 02,as indicated by dotted lilies in Fig. 7, to correspond with the quantityof material which is to be elevated by each belt as the materialdecreases in quantity from the head toward the tail of The buckets p aresecured t0 the belts by rivets r, which are provided with washers i",preferablyconstructedot'rubber or similar materiaharranged on the rivetsbetween the buckets and the belts, to permit the belts to adaptthemselves to the convex faces of the pulleys as the buckets pass aroundthe same.

The endless belts of the elevating mechanism are arranged farther awayfrom the boltiug-screen at the top ofthe screen than at the bottom, asshown in the drawings, in order to prevent the buckets from coming incontact with the screen by the sagging ot' the belts and to ati'ord thenecessary room for the upper wiperframe, E.

R is a scraper-plate, secured to the frame or casing of the machine andarranged to bear against the-upper sides of the lower pulleys, g q q2,between both parts of each belt, for the purpose of removing from thepulleys any meal which may adhere to their faces, and which would, ifnot removed,y accumulate, and thereby increase the size of the pulleysand strain the belts. The scraper-plate R inclines toward the descendingside ofthe belts, and discharges the material which is removed from thepulleys through openings R,fo1med in the belts between their ends, whichare secured together by straps R2, or other suitable means, so as toform these openings. If preferred,

however, the scraper-plate It may be inclined,

or curved lengthwise, so as to discharge the material over the outeredges of the end pulleys between the legs of the elevator-belts, when noopenings need be provided in the latter. i

IOC

Il: u

, Rais a flexible wiper or brush, attached to the lower edge of thescraper R, and bearing against the inner sides of the descendingportions of the belts, so as to detach any material which may adhere tothe belts. lhe material accumulates on the wiper until the openings Rarrive opposite the lower end thereof, when the material is dischargedthrough these openings. t

S represents delecting-boards, arranged in the upper portion of themeal-ehamber opposite the descending side of the head portion of theelevating mechanism. These boards are pivoted ats to the case, andconnected by a bar, s', which extends to the outside of the case,whereby the position ot` the boards can be adjusted so as to accelerateor retard the movements ofthe meal toward the tail end of the machine,as may be desired.

S' is a shield or guard-board, which is arranged above the upper edge ofthe boltingscreen B and below the lower ends of the deflecting-boards,so as to prevent the material from falling directly from the head of theelevatingmechanism upon the bolting-cloth, as this would tend to Wearthe cloth, and might force specks and impurities through the cloth. Theboard S compels the material, as it falls from the elevating-mechanism,to fall tirst upon the imperl'orate strip S2 above the upper edge of thebolting-surface,which strip is constructed of Wood or other suitablematerial, and re ceives the impact ofthe falling material. The latterdescends from the strip S2 without any sudden shocks over thebolting-surface. The descent of the material over the bolting-surfacemay be retarded on the coarser grades ot' cloth, it necessary, by cordst, secured transversely b v gluing or otherwise to the upper surface ofthese cloths.

U represents the feed-spout, through which the material to be bolted isintroduced into the case at the head of themachine; and U is thebrandischarge spout, arranged at the tail end of the bottom ofthecasing. The top A2 ofthe casing A is preferably covered with cottonfabric or similar material, which permits the escape of the vapor fromthe meal.

The machine is slightly inclined from its head toward its tail, wherebythe material is caused to move slowly from the feed end to the dischargeend of the casing in a well-known manner.
